Claims.

This invention relates to improvements in spinning frames, twisting frames and the like, and more especially to an improved means for mounting the cylinders which extend longitudinally of the spinning frame and around which the tapes pass that drive the spindles.

Heretofore, in order to remove a cylinder from the spinning frame, twisting frame and the like, it has been necessary to remove the cylinder longitudinally from one end of the frame and then to remove the cylinders successively from the frame. lt is often necessary to remove any one of the cylinders in a spinning frame, there generally being three or more, due to the bearings becoming worn or the cylinder being out of balance.

The primary object of this invention is to provide means whereby any one of the longitudinally extending cylinders may be removed from a spinning frame, twisting frame and the like, independently of the other cylinders and whereby the bearing block disposed between the proximate ends of any two of the cylinders may be removed or replaced as desired without the necessity of removing the associated cylinders from the machine.

It is another object of this invention to provide a head member for the proximate ends of the cylinder having a removable portion therein and to provide a bearing block in which the shaft disposed between the proximate ends of the cylinders is rotatably mounted and whereby the removable portion of the head member may be removed irom the proximate ends of the cylinders and the shaft along with the bearing blocks may then be partially rotated to where the opposite ends of the shaft will pass out of the opposite sides of the cylinders and may thereby be removed from the bearing block without the necessity of removing the cylinders.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which Figure 1 is a top plan view showing a plurality of the cylinders and showing portions of a spinning frame, twisting frame and the like, associated therewith;

01. sos-45)A Figure '7 is a vertical sectional view taken along the line 1 1 in Figure 5;

Figure 8 is an isometric view showing one of the removable sections removed from the head 5 member of the cylinder;

Figure 9 is a sectional plan view taken along the line 9 9 in Figure 5.

Referring more specifically to the drawings, the numerals il] and Il indicate the end frame members of a spinning frame, twisting frame and the like, and the numeral I2 indicates cross-bar portions of Samsons which are the intermediate frame members of a spinning frame or the like. in the present invention cross-bar portions oi the Samsons I2 areprovided with a suitable pin i3 located in the center thereof and projecting upwardly therefrom. This pin has slidably mounted thereon a bearing block broadly designated at I5. This bearing block I5 has outwardly extending base portions I6 having arcuate slots I1 therein which are adapted to be penetrated by screws I8 for securing the bearing block I5 to the Samson I2.

The bearing block I5 has a shank portion 2i) which is square in cross-section and which may be engaged by an open ended wrench for rotating the bearing block I5 about the pin I3 when the screws I8 are loosened for removing the shaft, to be later'described, which is associated with this bearing block I5.

The bearing block I5 has an enlarged upper portion 2l in which a suitable anti-friction bearing 22 is mounted and this anti-friction bearing 22 has a shaft 23 rotatably mounted therein. The opposite ends of the shaft 23 extend into head members broadly designated at 25 and being disposed at the outer ends of sheet metal tape cylinders 25. The head members 25 are preferably cast and each of the head members 25 comprises a bell-shaped portion 21 having 'its outer end ferruled as at 2S for securing the sheet metal cylinder 25 to the same. The bell-shaped portion 21 has integral therewith a boss portion Si] having a semi-circular cavity 3| therein which is adapted 4 5 to engage the shaft 23 adjacent one of its ends.

Referring to Figures 5, 6 and '7 it may be observed that the sheet metal cylinder 25 is cut away along the lines 35 and 36 and the head member 25 is cut away along the lines 31 and 38, thus forming an opening for receiving an insertable member broadly designated at 40 (Figure 8).

The insertable member 40 comprises a curved sheet metal plate 4I which conforms to the curvature of the cylinder 25 and has its right-hand end in Figure 5 recessed as at 42 and this recessed edge 42 is reinforced by a semi-elliptical strap member 43 which is curved to conform to the contour of the recess 42. This recessed portion d2 is adapted to cooperate with a semi-elliptical 90 recessed portion 45 in the periphery of the cyl- The insertable member 4U has a bo'ssportion 50 and an outwardly extending plate portion 5l which is cast integral therewith: and this outwardly extending plate portion 5| is bent upon itself to form a ferrule 52 which has the' same' radius as the ferrule 28; The left-hand end of the sheet metal plate vIH' is confined in -theif'errule 52 of the member fit. plate 4l extends to the points 55. The boss 5U of the member 4:3 has a semi-circular cavity 53 therein which conforms tol andl is adapted to engage'the shaft 23- as the insertable member 40 is inserted in the opening! defined by the lines 37 and' in the head member 25.

The boss portion 5D of the insertable member 4D'is penetrated by screws 54 which are threadably imbedded in the boss portion 38 of the head member 25 tothus secure the member 40 to the head member 25. The'. opening 41; heretofore described, is provided for inserting a suitable socket wrench orthelike therethrough for tightening the screws 54.

The description of parts refers to the bearings and shafts and the left-hand ends of the cylinders andlike'reference characters applyfto the righthand end of. alllof the cylinderswith the prime notation added.

Nowwl1en it is necessaryto remove a shaft 23 from any one of the bearing blocks. I5 or' it isnecessary to remove one or the other of the cylinders 26, it ismerely necessary to insert a socket wrenchor the like in the opening Hand to loosen the screws 54 which secure -the member 4D to the head member 25 and to thus remove the insertable member 4?; from the cylinder 26. The' same is true with the other of the-cylinders 2S adjacent the same so the bearing block l5'may be rotated. in the manner heretofore described to approximately 4'the position shown in Figure 4. When vthe opposite ends of theshaft 23 have passed beyond the recessed portion 45 on the cylinders 25, it is obviousthat'the shaft may be' withdrawn from'the bearing-block I5 and as a result, the proximate ends of the cylinders 26 would then be freeto remove `from the spinning frame',A if so desired, or a new connecting shaft can beV installed.

In the drawings'andspeciiication'there has been set forth a preferred embodiment of the invention, and although speciiic'terms are employed, they are usedA in a generic' and descriptive sense only; and not'foripurpo'ses of limitation, the scope of the invention beingdenned in the claims.
